My improved patients lift attachment is shown mounted on a hospital bed frame of conventional construction and design, all portions of the bed frame being omitted from the drawings excepting so much of the bed structure as is deemed necessary to show the connection of the invention therewith.

As shown, the bed frame includes two parallel and substantially rigid and inflexible longitudinal side members I rigidly connected at their ends by head and foot frames 2, thereby forming a rigid top frame for supporting the bed mattress (not shown). The rigid top frame is secured to and sustained by supporting legs 3 carried by rollers 4 having well known swivel connection with the lower ends of said legs. The lower end portions of the legs 3 may be connected and secured in rigid relationship by substantially rigid and inflexible frame members 5, as is well known. The mattress and the spring structure for supporting and cushioning the mattress are omitted because illustration thereof is unnecessary, for an understanding of the present invention.

My improved patients lift attachment for a bed of this or other form comprises a rigidly constructed frame including two duplicate frame members 6 having their end portions diverging upwardly from an intermediate connecting portion I and provided with vertically extended ends 8. These frame members Bl--8 are spaced apart and are connected by metallic bars 9 which may be attached to the ends 8 by welding II) or otherwise, as desired. The horizontal intermediate connecting portions 7 of these frame members are rigidly attached by a gearing frame or housing comprising a lower wall I I, a top wall l2, and end walls l3 and M integrally and rigidly connecting said lower and top walls II and I2. The lower Wall ll of the gear frame or housing is rigidly attached to the portions 1 of the two transverse frame members by welding l5, or otherwise. Thus, the gear housing or frame rigidly connects the inter-mediate portions of the two transverse frame members and cooperates therewith and with the bars 9 to form a rigid inflexible frame. The lower wall 5 I may be formed with an integral downwardly extended tube or sleeve it which is of such a length that when the device is attached to a bed for which it is intended, the lower end of said tube or sleeve is supported above and out of contact with the floor or surface on which the rollers 4 are mounted and operate. This leaves the bed freely movable from place to place while the attachment is in connection therewith.

A tubular shaft 32 has universal swivel connection 33 with the stud shaft 30. A crank device 34 has detachable telescoping connection 35 with the shaft 32, and may be secured in any longitudinally extended position by a set screw device 36. Thus, the combined length of the shaft 32 and crank device 34 may be varied as desired in order to adapt the invention for attachm'ent to beds of different lengths while the A screwthreaded shaft l1 extends downwardly into the tube or sleeve i6 through the open up per end thereof and through an axially alined hole 18 in the upper wall E2 of the gear frame or housing. In the specific form of the invention shown, the upper end of the screwthreaded shaft i1 is attached to a vertically movable transverse bar [9 by connections 'rigidly s'ecuring the shaft 11 and the bar 19 together. The bar 19 is formed with a U-shaped portion 2| adapted to receive within the upwardly openspace 2| a usual part of the bed structure (not shown) without interfering with the vertical movements of said bar IS.

The bar I9 extends laterally beyond the two side members I of the bed for which the lift'attachment is intended. Each end of the bar I9 has a vertically extended sleeve '22 which, when the device is mounted on a hospital bed 'or the like, extends upwardly beyond the outer side of the adjacent "side member 'I of 'the bed. A post 23 is telescoped within each sleeve 22 for relative longitudinal vertical adjustments, and may 'be rigidly secured in any such relative adjustment by a set screw 24 or other appropriate fastener. It is evident that the adjustable connection of the parts 22 and 23 may be variedas desired. The upper end of'each post 23 is rigidly attached to a horizontalr'od 25 forsupporting one or more flexible bands or sheets "25. As shown, the parts 28 are in the form ofndles'sbelts or bands engaged upon the end portions of the rods 25 at oppositeside's of the posts '23, and may be easily slipped on or removed from said rods. In the use of the device, it is intended that the bands or sheets 26 be extended across the upper side of the bed mattress and under the "patient so that the superposed and adja'c'entportions of the patient may be raised and lowered by raising and lowering said bands or sheets 25. A single band or sheet 26 may be used, or any needed number of such bands or sheets 'maybeused.

A gear wheel 21 has an elongated hub 28. The gear wheel is mounted within the gear frame or housing with the lower and upper ends of the hub 28 engaging the lower and upper walls I l and E2 of said frame or housing. The hub 28 is formed with a coaxial threaded hole and is screwed on the shaft 91 for vertical longitudinal movements when said gear wheel is rotated. The shaft l1 may be held from turning with the gear wheel 21 by any appropriate means, as by arms 29 projecting from the rigid frame and receiving the bar 19 between them. This leaves the bar. .I9 free for vertical movements by the gearing [1-21 while said bar is held from undesired displacement and thereby prevents undesired displacement of the bands or sheets 26. A stud shaft 30 is mounted for rotation in the end wall I4 of the gear frame or housing. A pinion 3| on said wheel 21.

studsh-aft is in'permanent'mesh with the *gear;

extended portion of the crank device 34remains available for operation close to one end of the bed. A bearing 31 for the crank shaft 34 may be provided with any suitable detachable device '38 for 'securingthesame to the bed frame.

Releasable hanger brackets 39 may be connectedwit'h the vertically extended portions 8 of the rigid frame by hinges 40 which permit swingin'giiioveinents of said brackets from and to posiward extensions 4! which prevent "any possible disengagement of the brackets frornthebed fram'e members I by lateral sliding movements of the lift device. If preferred, brackets 4'2'inay be detachably secured to the vertical extens i'ons'fl "of the frame by releasable bolt'fasteners '43 a'nd provided with downward extensions 44. The hinged brackets 39 may be provided atone-6r both ends of the liftatta'chment frame, as"desired. The use-of hinged brackets39 on at least one end or said frame is 'preferred'so'that said brackets may be "swung outwardly and disengaged from the bed frame to permiteasy disengagement of the oppositeend of the lift attachment from the bed frame; thereby dispensing with the necessity'of detaching'or removing the bolted brackets '42 rrom'one'end at least of'the device. 'It will be seen that these brackets are arranged in such a relationship that the lower end of the sleeve I6 is supported well abovethe level of "and out of contact with the floor "on which the rollers4 operate (Fig.2) so that 'there is no interference with the fr'e'e'movem'e'n't of tli'e bed about the hospital or'the like,

From the foregoing, theattachmnt of the device'to the bed for use is self-evident. Theb'ands 0r sheets 26 are extended across measures the bed below the patient and Cdn'fie'tdfiith the bars 25, preferably while the barrds'trsnetts 26 rest upon the mattress. 'I'hen th'fe gearing 3l -Z1 is operated to 'move'theshaft 'fl ldn 'ithdinally in an upward direction, "tlidfbv'fa mg the bar it and "the bands onshee'ts seamen had been secured on the bar's 25. mmsnswna movement of the bands or sheets '26 rai'ses th'e superposed and adjacent portions-of the b ody'of the patient above the mattress to'ai'iy' desired ex tent andfor any desired purpose. The mechanism is so arranged that downward -pressiire against the bands or sheets 26 by the w eig htof the patient supported thereby will not'dpfate said mechanis m norlower'th'e bands or sheets-26.
